Hi Jonathan, welcome to the forum.

In order to help you find a solution, we will need more information:

1. What version of FCP X and MacOS are you using?
2. What computer are you using?
3. Are you using an external drive for you media, or is everything stored on your computer?

Thank you mr Ronny,
My Final Cut Pro X version is 10.2.3
My Mac OS is Yosemite
My computer is iMac (21.5-inch, late 2012)
I store all my projects in my computer

I saw my projects when I went to 'file-open library-Macintosh HD's projects and events 20160921_1409_GMT+1.fcpbundle.
But they are all showing the caution sign on them all, I opened it and it's not displaying properly with offline files which are already in fcpx, like the inbuilt songs and sounds. Also, my render files are heavy like up to 250gig. It's not deleting as I went to 'file-delete generated library files-and delete all. But nothing happen. I just have 18gig left on my hard disk.
Thank you

Hi Jonathan,

Try this:

Close FCP X.
Launch FCP X again while holding the ALT + CMD keys pressed down.
You will get a message asking if you want to delete your FCP X preferences. Confirm and let FCP X launch.
Then open your Library and see if this has solved the issue.

the same has happened to me, working on a project for over 13 hrs and crashed and won't reload. i have the latest fcpx and iMac 27". iv noticed that the video is showing red just before it crashes, also i only have 18 gig left on my hard drive i wondered whether that is causing it?

i have also lost my project, i see just before it crashes red media where my clips once were. every time i restart the project or different backups it instantly crashes, its will load projects from months ago for a while then crashes after a minute. iv noticed i have 18 gig left own my hard drive and wondered if that was causing the problem. iMac 27" iMac (Retina 5K, 27-inch, Late 2015) 3.3 GHz Intel Core i5 8 GB 1867 MHz DDR3 this is a project for a golf course and can't afford too lose it. any ideas.

Hi Steve,

Some questions:

Is your Library stored on your internal hard drive and are your media stored inside the Library?

Is it your internal hard drive that only has 18GB left?

Select your Library in Finder and press CMD+I. What is the file size of your Library?
